title: [A new type of headache of ocular origin: ophthalmotonic headache. Diagnosis and treatment].
abstract: BACKGROUND
  In some patients it was seen that chronic headaches disappeared after laser iridectomies had been done to prevent glaucoma, in persons with normal intra-ocular pressure (IOP).
  
  
  OBJECTIVE
  To make a study of patients with headache, some of whom were treated with topical beta-blockers (carteolol) and others by Yag-laser iridectomies. The effect on headache and IOP was analyzed.
  
  
  METHODS
  A survey, ophthalmological examination and headache provocation test were carried out in patients with headaches, and the changes in IOP determined by pharmacologically inducing miosis and mydriasis were recorded. Three treatment groups were formed and the results analyzed statistically.
  
  
  RESULTS
  In the 12 patients treated pharmacologically, 62% improved and in 14% the headaches disappeared. In the 16 treated using laser 94% were cured and 6% improved. When both types of treatment were used on 9 patients, 22% improved and 78% were cured. The validity of the ocular pressure curve was checked in the diagnosis of blockage of the pupil.
  
  
  CONCLUSIONS
  Some headaches of ocular origin (ophthalmotonic), not previously described, occur due to abrupt changes in intraocular pressure, and improve significantly when the IOP is reduced by beta-blockers or Yag-laser iridectomies are done. A valid provocation tests for diagnosis of this type of headache is described. We consider that blockage of the pupil and/or of the angle of the anterior chamber are possible etiopathogenic mechanisms.
